This new review explains why soft sweeps are the bane — and the baseline — of ecological genetics
If you’ve done ecological genetics research in the last decade, you’ve almost certainly cited a series of papers by Pleuni Pennings and Joachim Hermisson, which broke down the problem of soft selective sweeps. Pennings and Hermisson have revisited soft sweeps … Continue reading

#Evol2017 catch-up — Effects of range expansions on mating system
Two weeks (more about that in a post I’ve written for Wednesday!) after the closing day of the 2017 Evolution Meetings, the Molecular Ecologists have all dispersed from Portland, though some may have left things behind! Still, the conference was so … Continue reading

When less might be more: The evolution of reduced genomes
The advent of affordable genome sequencing has provided us with a wealth of data. Researchers have sequenced everything from Escherichia coli (4.6 Mbp genome size), to sea urchins (810 Mbp), chimpanzees (3.3 Gbp), and humans (3.2 Gbp). Then there are the … Continue reading

Shared patterns of genomic diversity across populations of distantly related taxa
Genomic diversity is shaped by the complex interplay between the effects of genetic drift and natural selection among populations. Several of these effects, especially those of linked selection at neutral sites, adaptive introgression, and barriers to migration (often called “genomic … Continue reading
